Some info:

Logging in:
To log in or register, simply use the username and password fields to the right. If the user does not exist, it will be created and you will be able to select your starter element. Note that a new user will get some free packs from the store.

AI:
4 AI levels, Commoner, Mage, Champion and Demigod. Mage and Demigod have premade decks, Commoner and Champion have generated deck. They are roughly in strength with AI2, AI3, AI4 and FG.

Trading:
Put someone's name in the 'Challenge' box and click Trade to send a trade request. Once they do the same, the trading form open. One player first selects a card, that card is then showed to the other player who then selects a card. Both players click confirm and the trade is done. NOTE: Nymphs and Marks can only be traded for other Nymphs/Marks. The starter deck, oracle cards as well as the cards you get from the free packs in the beginning are account-bound and cannot be traded.

Chat:
Just use the chat box at the bottom. You can chat when not logged in, you will then have the name "Guest_Name" where name is either the name in the username box, or, if empty, a random number. Commands: "/w username message" sends the message only to the user with the name username. "/who" gives you a list of all online users. Does not list guests.

Booster Packs:
When you choose an element, each card in your pack has a 50% chance to be of that element. Everything else should be self-explanatory.

Almost everyone posting in this thread (Feedback/Suggestions/Balance)

Spoiler for Implementation Differences:

I'm unsure about
Permanents are processed before creatures. Weapons still attack last

I don't intend to fix
Mutants/Eggs can become any creature (even SoFo. If there's issues with shardless meta, I'd rather implement card sets and restrict these cards with those)
Skyblitz buffs Phase Dragons
Unstable Gas destroys Cloak
PU Mutant doesn't remutate/rebuff. Hatch doesn't result in a mutant
Lobo'd Steam Machines still lose attack
SoBr won't have your opponent keep drawing if your hand becomes full
Marks don't stack on your original mark, aren't limited to 6
Endow copies status, so copies adrenaline and delayed

Differences I mention for completeness, but which really don't matter
Immaterial, Psion, Momentum are statuses applied on play (still loboable)
PU Wyrms reset their attack. PU Scarabs don't burst their health
Adrenaline applies on hit effects for first two attacks, not first/last
Miracle won't damage you if you're at maxhp
Stoneskin's cost applies after maxhp is raised
Canceled actives don't still cost quanta, you can cancel discarding
Negative health vs Skull Buckler becomes a skeleton
Antimatter isn't blocked by Wings or Gravity Shield
Creature stats aren't capped (Player max maxHP is still 500)
Singularity randomness is different (notably, doesn't unantimatter self (instead attacks self) & may equip owner with dagger)
PU doesn't restore airborne
SoW Seraph doesn't lose spelldamage (is loboable)
Removal of arbitrary "Elite" and "Improved" prefix
Can't target Chimera with Mitosis or PU
Automulligan reshuffles whole deck, rather than remaining deck and leaving mulligan inducing hand as top 7 cards of deck Paris Mulligan
Marks are in element (no random nymph from NT)
Malignant Cells don't attack when spawned past currently attacking cell

Spoiler for Changes. Unsure whether nerf or buff:

Quanta cap raised to 99. Paris Mulligan
Venom vs gpull'd target inflicts poison
Weapons transfer CC Shield effects to player (Ice Shield freezes weapon, Procrastination delays weapon, Fire Shield damages wielder for 1hp, Spine Carapace poisons)
Random quanta is proportional (Twice as likely to select over if there's twice as much as )
Sword doesn't have an active (This, along with Titan, may be too strong with Crusader+Luciferin+Hope)
Playing a weapon over a frozen/delayed weapon clears the frozen/delayed status
PU Doll repeats all statuses
Multiple actives
SoG heals 4 regardless of mark
SoD raises maxHP by 24 & heals 16 regardless of mark
SoR removes summoning sickness for all creatures, doesn't allow creatures to double cast. Cost reduced by 1. SoR diving doesn't multiply with itself
Sky Blitz & Chimera are rare cards

Spoiler for Buffs:

Cockatrice is airborne
Flying Weapon can be cast on opponent

SoI grants +2|+2 / +3|+3 per shard, irrespective of type. Note that since multiple passives/actives is possible, Shard Golem can be a better spell caster in openEtG

Not exactly a nerf: Dessication's effect is the same as Dry Spell, but costs . This steps away from conflicting with Thunderstorm & Flooding, and feels more suitable given the other changes made to
SoW only grants +3/+0

To Zanzarino: openEtG devs do not intend this project to be disrespectful to you, but rather to be an expression of their admiration & enjoyment of the game you created. If you disapprove of the existence of this project, all devs have agreed to cease work on openEtG at your request.

[serprex]

I should probably move that up to the "on the fence tier"

Essentially it's the result of applying burrow's halving when calculating trueatk. Adding eclipse could be done after the halving, which is currently the last step, & SoPa would have to apply its buff to a separate variable besides base attack

Alternatively, with a more consistent burrow behavior, it may be possible to find some better design for Antlion that isn't forced to be a gimmick. I'm open to any discussion of differences' merit. That I don't intend to change something doesn't mean I'll refuse

[Fippe94]

Personally I believe that burrow'SoPa is a good synergy that should not be removed.

[farscape]

Is this supposed to be an eventual replacement for the current game, taking over the development ?

If yes, does the developer of the original know about it and is he OK with it ?

I know there isn't very active development and there are certain bugs and server issues that need fixing, but I still feel that a one-sided (hostile) take-over might run into legal problems.

[serprex]

@Fippe
I concede. It'll be a bit backwards seeming in the code when I implement SoPa to grant +4/+2 to burrowed creatures

@farscape
Zanz hasn't been online since I began this. I believe there to be no legal issue: the code is mine, & I intend to make no use of Elements's graphics/audio (currently using images from http://dek.im/resources/card_header_images but I'd like to end that use sooner rather than later)

This isn't a hostile take over (I have no interest in purchasing Zanz's assets). While I'm open to discussion of legal issues, I'd prefer to not derail this topic which is intended to focus on development. I'm not interested in legal superstition

[andretimpa]

From a legal point of view I think this is okay as long as it is not for commercial purposes (since serprex and AA are not stealing the code, but reverse engineering it). Making a profit out of it would probably characterize plagiarism (not the case).

I do approve of this as it could be used in future emergencies (see War and server bork for example). Unfortunately I don't know enough Javascript to contribute beyond proofreading the logic in some parts of the code.

[CuCN]

Graboid's 2 attack is essentially 1 due to being burrowed

Easy fix: change attack from 2 to 4.

[Tsmuji]

Graboid's 2 attack is essentially 1 due to being burrowed

Easy fix: change attack from 2 to 4.

I wouldn't complain at a nerf to graboid, however slight. :p

[Gandora]

I would love to participate in the development But I have yet no knowledge of JavaScript And I don't have any experience with Github ^^ I guess I will spend some time learning it. If you know a good tutoring link, please let me know I can't promise that I can help a lot or even will work a lot on it, but if I find some time I'd really love to help you out

[Keeps]

Legal information, copy pasta:

You can copy all of gameplay without any issues at all. That is not copyrightable or enforceable. The things that matter are assets - art, sound, music, video, etc. There are loads of examples of this in the industry, for example first Warcraft basically copied Dune 2 gameplay mechanics and the genre was totally new at the time. For a more recent example - check out Gameloft company, the developer for iphone. What they do is copy successful game ideas as close as possible to the original but without using any art assets from originals. That is their successful business model. They copied games like Halo, Starcraft, World of warcraft and so on with huge success in their field. It is even funny that if you check their wow clone you may see that animations of orcs and their looks are very close to the original but technically aren't. 

TL;DR version: As long as you copy gameplay and don't copy any assets (art, music, animation) you are 100% fine.

Programming ability isn't necessary to help. Testing & graphics can be done without programming experience
One might think that openEtG being the first time I get something working with HTML5 tech would imply I'd have recent experiences to share on learning, but they'd be wrong. Anti sent me some links when I started, but they mostly went over my head. Honestly, I'd suggest reading openEtG's code as a way to learn (which means you'll be learning all my bad habits, but eh)

I should probably document the code
